How to use

Place the calculator on a flat surface and ensure the solar cell receives light for optimal power. Use numeric and arithmetic keys for calculations; use M+ and M− to add to or subtract from memory, MR to recall memory and MC to clear it. Use GT to view cumulative totals, percent and square root keys for respective calculations, and ON/C or CE to correct entries. Turn off manually if needed to conserve battery.

Recommendations

Keep the solar cell clean and avoid prolonged storage in complete darkness to preserve battery life; replace the LR1130 battery when display dimming or unreliable operation occur.
